Nanomaterials Up Close: Cobalt oxide superlattice (w/video)
|

(Nanowerk News) "These individual particles of cobalt oxide have been engineered to form a superlattice or 3D mesh structure to improve their chemical activity," explains Giorgio Divitini.

"We are designing cobalt oxide assemblies at the nanoscale to improve their properties as a catalyst - a material that speeds up a reaction. We're using the material to produce hydrogen and oxygen from water, contributing to the development of new sources of fuel and energy.
|
|
Being able to make tailored structures at the nanoscale is very important for catalysis and has important applications in everyday life, from electricity generation to sensors and manufacturing processes.
|
|
In my research I study what such structures look like, using state-of-the-art electron microscopes that can push the limits of science, allowing individual atoms to be imaged and identified."

'Nanomaterials Up Close' is a special series linked to the 'Under the Microscope' collection of videos produced by Cambridge University that show glimpses of the natural and man-made world in stunning close-up.
